>>3348516I have a manual Vivitar 28mm f/2.5 and I think it is better suited for landscape or indoors. Like inside a subway car where you want to get a lot in frame, but the distances are rather short. Of the manual lenses I have on my 1.5x crop,
Vivitar 28mm f/2.5 (42mm equiv): Better for indoors.
Vivitar 35mm f/2.5 (52.5mm equiv): Good all around when you are approaching people.
Nikkor 50mm f/1.4 (75mm equiv): Good for tighter, but close portraits and general street.
If I had a full frame camera, I'd need to relearn everything for the focal lengths and their FOV/AOV.
